Transactional Processing Systems (TPS) are systems that automate transactions, most commonly, EFTPOS/Payroll/MYOB. These systems are used at lower levels of organisations as they are the basis for analytical systems.
Decision Support Systems (DSS) are used at higher levels of organisations, they help managers make decisions particularly in relation to more complex problems. DSS provide data for analysis in an organisation, and through the use of complex modelling, also allow managers to solve business issues more efficiently.
Describe the three quantitative models typically used by decision support systems.
There are 3 quantitative models used by Decision Support Systems include:
Sensitivity Analysis which is the study of the impact that changes in one part of the model has on other parts of the model. If the model is sensitive then a company could expect to see a decline in sales.
What-If Analysis checks the impact of a change in a proposed solution.
Goal-Seeking Analysis finds the inputs necessary to achieve a goal. This model looks to the end result and works backward to achieve the final goal.

Describe a business processes and their importance to an organisation.
A business process is a standard set of activities that accomplish a specific task, such as processing a customer order.
An organisations business processes must be studied, understood and continuously improved because an organisation is only as effective as their employed processes.
Compare business process improvement and business process re-engineering.
Business process improvement deals with a continuous improvement model which attempts to understand and measure the current process to implement improvements accordingly.
Business re-engineering on the other hand, is the analysis and redesign of workflow within and between the business. Business re-engineering assumes the current process is irrelevant or does not work and starts building from scratch.

Describe the importance of business process modelling (or mapping) and business process models.
Business process modelling (BPM) is the activity of making a detailed flowchart or process map of work processes. BPM is important as it aims to show process details in a gradual and controlled manner.
Business process modelling and business process models, bring visibility to technology, encourage consciousness of what people are doing in a business and enable analysis.
